Common Ground MCP

An MCP server that leverages Qloo's taste graph to recommend shared entertainment or dining options for a group. It supports two main flows: planning a multi-stop night out (dinner, drinks, live music) based on friends' favorite media, or finding a single common item like a movie or restaurant. It integrates with agents via Streamable HTTP.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

find_common_ground — Find common ground for a group
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Pick ONE movie, TV show, book, music artist, podcast, restaurant (kind=place, with location) or destination that a whole group will enjoy. Give each person's name and 2 to 5 things they love. Favourites can come from another category with tasteFrom, for example music artists to pick a restaurant, or any for a mix of artists, movies, TV shows and books. Uses Qloo's taste graph to score every candidate for every person and returns the option that makes the least happy person as happy as possible, with a reason per person.

plan_night_out — Plan a night out for a group of friends
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Plan dinner, drinks and a live music venue in one city for 2 to 6 friends. Give the city and each friend's name with 1 to 4 music artists, movies, TV shows or books they love. Optionally give an exact night date as YYYY-MM-DD; Qloo then filters venues by that date's weekday only, not by exact opening times, travel or availability. Qloo's cross-domain taste graph turns that shared taste into real venues. Each stop is the venue whose least happy friend is happiest, and Qloo explainability names the favourites behind it, with the share of each friend's taste.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http common-ground-mcp https://common-ground.lipmichal.workers.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add common-ground-mcp --url https://common-ground.lipmichal.workers.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable common-ground-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "common-ground-mcp": {
      "url": "https://common-ground.lipmichal.workers.dev/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "common-ground-mcp": {
      "type": "streamableHttp",
      "url": "https://common-ground.lipmichal.workers.dev/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start common-ground-mcp and inspect its tools.

      "url": "https://common-ground.lipmichal.workers.dev/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http common-ground-mcp https://common-ground.lipmichal.workers.dev/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

  "mcpServers": {
    "common-ground-mcp": {
      "url": "https://common-ground.lipmichal.workers.dev/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "common-ground-mcp": {
      "serverUrl": "https://common-ground.lipmichal.workers.dev/mcp"
    }
